Answer 1

:) I have to write something to submit.

Answer 2

see below

Explanation:

The sine of an angle is the same as the sine of its supplement. You know π radians is 180°, so the supplement of an angle in radians is that angle subtracted from π.

sin(π(a/11)) = sin(π(11-a)/11)

For example,

sin(π/11) = sin(π(11-1)/11) = sin(10π/11)
